2 Claims.

This invention relates .to a functionally an structurally improvedclosure. 7 i

It is an object ofthe invention to provide an article of this charactercapable of use in numerous associations, but primarily intended for theypurpose of sealing vessels suchras for example, bottles, and by meansofwhich the contents thereof will be effectively prevented from wescaping by evaporation or otherwise.

Another, object of the invention is that of providing a closure whichmay be unseated with minimum effort and which closure will, despitesevere stress, have its component parts remain a in properly assembledcondition.

Another object of. theinv'ention is that of providing a closure whichmay have associated with it a swab and the construction of which closurewill besuch that the swab will remain as a unit thereof throughout theentire life of the article.

An additional object is that of providing a closure, the construction ofwhich will be relatively simple so that the device may be manufacturedto the greatest extent by automaticmachinery. Moreover, this device willembody rugged characteristics so that maximum life will be incorporatedwithin the same.

With these and other objects in mind, reference is had to the attachedset of drawings il- 0 lustrating practical embodiments of the inven-Figs. 6 and 7 illustrate additional structures which may be includedwithin the teachings of the present invention.

While a closure constructed in accordance with the present invention maybe manufactured of many different materials, it is preferred that it beformed of a moldable material such as bakelite, or other phenol product.Such materials lend themselves especially to the construction ofclosures which should be moisture and air-proof and are to be capable ofwithstanding rough usage.

Thus, referring primarily to Fig. 1, the numeral l0 indicates a closureformed of a disklike body having a downwardly extending flange lladjacent its outer edge and the exterior face of which, as in Fig. 4:,maybe serrated to provide a roughened surface [2 by 5 means of which thecap may be readily gripped and manipulated. The area of this cap should,in the embodiment under consideration, be adequate to insure that thepouring lip ofthe loottle is enclosed withinthe flange. ,The latter isconcentrically disposed with respect to a sec ond flange l3 whichdefinesthespace within which the plugor stopper M is to be disposed; Thissecond flange has a radius such that it N lies within the neck ofthebottle and it will consequently be appreciated that the entire lip ofthe receptacle is thus effectively protected. With a view to securingthe stopper to the cap it is preferred, according to the presentinvention, that a series of spaced annular grooves I5 be formed in theinner cap face to provide trough portions within which cement or similarmaterial may be keyed for the purpose of preventing a dislodgment of thestopper or plug I l. Obviously, the latter may be formed of any desiredmaterial as, for example, cork and with the construction aforenoted itwill be observed that not alone is the pouring neck of the bottleprotected adequately, but also that it is possible to secure a majorpurchase on the outside of the flange in order forcibly to dislodge thecap and plug from association with the bottle, and the plug or stopperwill remain coupled to the cap even under most strenuous conditions ofuse. 0

With a View to assisting the withdrawal and insertion of the plug orstopper, it is preferred that the latter as in Fig. 1 be formed with abore 16 which will break the vacuum or pressure except under finalstages of sealing or initial stages of withdrawal. The same results maybe achieved by, for example, forming a groove H in the side Wall of theplug or stopper.

Closures of this nature are quite often employed in connection with areceptacle, the contents of which require the use of a swab.Considerable difficulty has been experienced in securing such an elementagainst accidental displacement. In order to overcome this objection,

it is proposed, when necessary, to apply an element of this nature tothe closure that the cap of the latter be extended as at I8 in Fig. 2and and passed to extend through the fibrous body W of the former as hasbeen indicated in Figs. 2 and 3.

The teachings of the present invention and more especially the couplingof the rod to the cap are not limited to the construction shown in Figs.1 and 2. For example, the cap 2|, as

shown in Fig. 5, may have a bored extension 26 for the purpose ofaccommodating the ro d ifi.

Where this construction is resorted to, it is ob-' vious that arelatively deep groove is provided for the reception of a cement orsimilar material to retain the plug applied to the cap. As indicated indotted lines, a complementary extension 21 might extend from the uppersurface of the cap in order to assist in manipulating the same. Also, ifdesired, the rod as at 28 in Fig. 7 might be molded integrally out ofthe cap, material. However, due to the liability of breakage it isusuallypreferred that the rod be a unit or element separate from thecap.

As at 29 in Fig. 6, a cap of the general type shown in Fig. might, ofcourse, be constructed without employing a rod structure in associationtherewith. This cap might, moreover, be provided with an extension 21 aspreviously described.

Where, however, a rod I9 is employed, it is preferred as shown in Figs.2 and 5 that the rod be formed with a relatively extended portion orportions as at 30 and around which at the time of forming the cap, themoldable material is caused to extend. Thus, while in certain instances,it might be feasible to rely solely upon frictional contact of theparts, there is provided by the construction just describedor itsfunctional equivalent, an anchoring provision which will preventcompletely any danger of accidental displacement.

With structures such as the foregoing, it will be appreciated that amongothers the objects asspecifically aforenoted are achieved. Obviously,numerous changes in construction and rearrangements of the parts mightbe resorted to without departing from the spirit of the inven- "tion asdefined by the claims.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

l. A closure including a cap, a plug secured to the inner face of saidcap, a bored extension forming a part of said cap and a swab mountingrod extending through said plug and having frictional engagement withsaid bore, the outer end of said rod being split and extending angularlywith respect to the rod body.

2. A closure including, in combination, a cap, an extension projectingfrom the inner face of said cap and integraltherewith, said extensionbeing formed with a bore, a swab-mounting" rod extending into said bore,an enlargement form'- ing a part of said rod and within said bore tolock the same against displacement, and a plug formed with an'openingfor the accommodation of said rod and secured to the inner face of saidcap, said rod lying in contact with the face of said plug opening. 7
